Convert the posted mass from oz → g
using the following formula 1oz. = 28.3 g

Take the mass measurement of the rubber
stopper on the metric balance.

Do this for four different rubber
stoppers with different posted masses (each table member should do all
parts of the experiment for at least one sinker)

Subtract the measured mass in grams
from the posted mass in grams to determine the relative error.You may disregard any negative numbers9
take an absolute value of your result).

Take the relative error in grams
and divide by the converted posted mass, in grams, and multiply by 100 to
determine the percent error.

Observations:

Analysis:include your calculations and math work for doing the oz-g conversions,
relative and percent error.

Make a Bar
graph of actual versus converted mass values of the rubber stoppers used.

Conclusion: (restate
the hypothesis, explain how you answered the question or not and compare
numeric results to prove or refute your hypothesis, discuss observations as
possible errors and propose a next step and who outside of this science class
might care about your results)
